This paper presents an improved software estimation model, which uses to estimate developing effort of e-Learning's contents. This model is called the e-Learning courseware Effort Estimate Model (EEEM). This model uses special designed storyboard to delineate the e-Learning courseware's contents and define the measurement metrics. Research was conducted using statistical data from the real worl...

This paper investigates proposed code-based measures for multimedia courseware as part of an on-going program of research into effort estimation models. The proposed code-based size measures are analysed using source code and project data from WinlEcon courseware written in the ToolBook authoring language. Statistical analysis of a priori, ToolBook specific and portable subsets of 47 code measu...

Software estimation cost drivers are in many cases abstract concepts that are better estimated by breaking them down in a number of second– level aspects. This raises the need for inquiry regarding the most appropriate aggregation processes for them, since they significantly impact in the final cost estimates. Recent research on aggregation operator design has resulted in a number of families o...

Analogy-based estimation seems be a very promising estimation methods. A large Norwegian IT consulting company is going to use analogy-based method for further effort estimation. Thus, a historical project database must be built. Several issues have come up when discussing the feasibility of building such a project database. One challenging issue is which projects should be involved in the data...

This paper aims to provide the software estimation research community with a better understanding of the meaning of, and relationship between, two statistics that are often used to assess the accuracy of predictive models: the mean magnitude relative error, MMRE, and the number of predictions within 25% of the actuals, pred(25). We demonstrate that MMRE and pred(25) are, respectively, measures ...

Business Process management Systems (BPMS) are highly integrated in the IT of organizations. They are at the core of business. Thus, migrating from one BPMS solution to another is not a common task. However, there are forces that are pushing organizations to do this step, e.g. maintenance costs of legacy BPMS or needed additional functionality. Beforehand, risk and effort must be evaluated. Thi...

In this paper, we present the main goals, questions and hypotheses of our research related to test execution effort estimation. Here, we introduce a model that we developed for estimating test execution effort based on the test characteristics and risk factors. In addition, we presented the planning of empirical studies for this model. These studies have the objective of configuring, calibratin...

The object-oriented modeling has been largely adopted in industry in the last years. Several systems built 4 or 5 years ago may need an adaptive maintenance process in order to better satisfy market and customer needs. In this paper1, a model for effort estimation/prediction of the adaptive maintenance is presented. A selection of metrics for effort estimation has been applied to the general mo...
